    Abstract: A method of masking sounds associated with a vehicle is provided. The method includes performing on processing circuitry, monitoring of vehicle data. A tonal disturbance type and a tone to mask associated with the tonal disturbance type are identified based on the vehicle data. A shaped band of sounds is determined based on the tone to mask. The shaped band of sounds covers a range of frequencies around the tone to mask. The shaped band of sounds is applied to an audio output of the vehicle.

    Abstract: A method of controlling a power inverter coupled to an electric motor in a vehicle powertrain having an engine is provided. The method includes generating a voltage waveform signal and a switching frequency signal for the inverter via a controller. At least one of the voltage waveform signal and the switching frequency signal is at least partially based on at least one commanded engine operating parameter. For example, the engine on/off state, engine torque, and engine speed can be considered. A vehicle having a controller configured to implement the method is also provided.
